APPARATUS FOR COpOLlNG BEER.

SPECIFICATION forming part of Letters Patent No.r298,07l, dated May 6, 1884.

Application filed February 1Q, 1884. (No model.)

.T0 all whom, it party concern.-

Be it known that I, HENRY E. DEoKEBAoH, a citizen of the United States, residing at Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Apparatus for Cooling Beer, of which the following is a specification.

The object of Iny invention is a device for cooling beer that will occupy buty little space in the vessel and present the greatest coolingsurface to the beer, so as to economizethe cooling-agent, and at the same time rapidly perform the duty required. Its object is also a device that can be readily converted to use either water alone or the cooling-agents used inconnection withvthe ordinary refrigerating apparatus used in breweries, or both agents combined. A

/Vith these objects in view my invention consists in a double or jacketedcylindenwith suitable connections for the cooling agent or agents, these connections being detachable, so that either or both methods of cooling may be employed, as desired.

The invention will be rst fully described in connection with the accompanying drawing, and the novel features particularly referred to in the claims.

The drawing is a central vertical section of a beer-vat provided with myimproved cooler, which is also shown in central vertical section. The cooling-surfaces are an outer cylinder, A, and an inner cylinder, B, made of light sheet metal. The two cylinders are united at top and bottom by metal caps G, preferably of cast metal, leaving a closed chamber between' the two cylinders. The cooler so constructed is placed centrally in the vat D, being mounted upon feet E above the bottom of the vessel, so as to permit a free circulation of the liquid contained in the vat to the inside of cylinder B.

Within the chamber F, between the two cylinders A B, is a coiled pipe, G. The upper end of the coil or worm G is connected to a pass the pipe I or any pipe through the lower cap C and bottom of the tub, the lower end of the coil may be returned and passed out of upper cap; and this plan I prefer when the brine or cooling-agent is forced by a pump through the coil and returned by the same force to the` refrigerator. I have shown upon top of cap C a screw-plug, c, and there are two of these opposite each other upon the cap, to permit the circulation of air through the chamber F when the liquid from the refrigerator is alone used. I Iind it, however, of great advantage to use both the refrigerating-liquid passed through the pipe or coil G and water used in the usual manner. In this case the water` is introduced into the chamber F around the coil G by means of a pipe, as J, at the bottom of the device, or by a pipe at top, as shown in dotted line. Y

Instead of passing a continuous iiow of water through the chamber F, the chamber may be simply filled with water or other substance, to act as a conductor to convey the temperature of the pipe-coil G to the cylinders A B. Then Water alone is to be used as the coolingagent, the top cap is removed and the coil G lifted out, after which the cap is again secured in place. The pipe H in this case will serve as the discharge, its upper end being of course disconnected from the refrigerator-vat, and the water is introduced, either through one of the pipes IJ at the bottom of the vat D or through the pipe shown in dotted line, from the top to near the bottom of the cooler. I prefer the latter form, as in this casethe pipes I J may be dispensed with and no opening is necessary in the bottom of the vat D. Besides, the joints between the pipes and cooler A B C maybe more easily kept packed and any leakage readily detected.

The chamber F is made air-tight or tight enough to prevent any leakage from the coil or chamber passing into the beer. If the coil is made perfectly tight, it may be used alone as a cooler; but to be entirely safe the incased coil is preferred. Besides, the coolingsurface is more and the circulation of the liquid in the vat better with the cylinders than if the coil alone is used.

I do not limit myself to the particular mode shown for closing the ends of chamber F and uniting the Atwo cylinders, but think it is the IOO of the vat, to support said lower end above said bottom, substantially as described.

2. In a device for cooling beer, the combination, substantially as specified, of the two cylinders AB, one within the other, and closed at both ends, forming the closed chamber F, with the coil G, located within said chamber, and induction and eduction pipes passing into said chamber and connected to the respective ends of said coil.

3. In a device for cooling beer, the combination, substantially as set forth, of cylinders A B, caps C, and coil G, with the two induction-pipes connecting, respcctively,with coil G and chamber F, and two eduction-pipes leading one from the chamber and the other from the coil, for the purpose of cooling at the same time by means of the refrigerati ng-liquid and water.
